Through close study of Avicenna's statements and major works, Dimitri Gutas traces Avicenna's own sense of his place in the Aristotelian tradition and the history of philosophy in Islam, and provides an introduction to reading his philosophical works. The Second edition is completely revised and updated, and adds a new final chapter summarizing Avicenna's philosophical project. It is also enlarged with the addition of a new critical inventory of Avicenna's authentic works, with additional information on all manuscripts and important editions and translations.
